Application led April 2, 1921. Serial No. 458,134.

ing at Parkersburg, lin the county of Wood and State of West Virginia, have invented certain new and useful Improvements in lWindow-Cleaning Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in window cleaning devices, and it is an obj ect of the invention to provide a structure of this general character having novel and improved means whereby the pane may be conveniently and effectively wiped when the occasions of practice may so necessitate.

Another object of the invention is to provide a novel and improved device of this general character wherein the stiles are slotted, with carriages riding within the slots, and said carriages being connected by wipingelements for contact with the opposed faces of the window pane. v

An additional object of the invention is to provide a novel and improved device of this eneral character including slotted stiles 1n each of which is slidably arranged a carriage for a wiping element and wherein means are provided for closing said slot when the carriage is substantially at the limit of its movement in one direction.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved window cleamng device whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of -my invention will hereinafter be definitely claimed.

In order that m invention may be the better understood," will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in elevation, with portions broke'n away, of a window cleaning device arranged in accordance with an em-l bodiment of my invention;

Fig. 2 is an enlarged fragmentary sectional view taken throu h a side marginal portion of the device as i lustrated in Fig. 1;

.Fig 3 is an enlarged fragmentary sectional view taken through the upper portion'of the structure illustrated in Fig. 1

Fig. 4 is an enlarged fragmentary vertical sectional view taken through the up portion of the device and illustrating the wiping elements; and

Fig. 5 is a fragmentary view in elevation of an end portion of the tubular member comprised in a wiping element.

As disclosed in the accompanying drawings, R denotes the upper rail of the window structure and R the lower rail. The opposite end portions of these rails R and R are connected by the stiles S. Each of the stiles S comprises a pair of transversely spaced strips 1. Overlying the outer edges of the strips 1 of each stile S and secured per V therealong, as at 2, by screws or the like is a'metallic plate 4, said plate bridging the space between thestrips 1. The opposite en ds of the metallic strip 4 are provided with the right angular extensions 5 overlapping the outer edges of the rails R and R and suitably secured thereto by the screws 6 or the like. By this means, a rigid and strong sash frame is provided.

The rails R and R. are also connected by the supplemental stiles S positioned in close proximity to but slightly spaced from the inner margin of the main Stiles S whereby the side portions of the sash structure are provided with the vertically directed slots 7 extendin the entire distance between the rails R' and The marginal face or edge of each of the supplemental stiles S opposed tothe adjacent stile S at its transverse center is provided therealong with a groove or channel 8 herein disclosed as V-shaped in cross section while the opposed longitudinal edge or face of said stile S' is .provided with a groove or rabbet 9 to receive the marginal portion of a window pane P.

Coacting with each pair of stiles S and S is a carriage C. This carriage is preferably of metal and is substantially U- shaped in cross section with its intermediate portion or base portion 10 arranged within a slot 7 and with its side members or wingsll overlying the side faces of the su plemental stile S ecured to the outer face of each of the side members. or win 11 is an inwardly facing bracket 12, sai vbracket providing a mounti for one end portion-ofa wiping element l As herein disclosed, a wiping elementE is arranged at each side of the pane P. and

'.each of the 'elements El .comprises an elonwithin the tubular member 14 throughthel slot 15. A rod 2O is then placed within the iso,

gated tubular member 14t having extending therealo, `a slotv 15, the longitudinal marg'ins of said s lot substantially entirely therealong' being 4defined by the outstandin flanges 16. Enga ed with the opposite en portions of the tu ular member 14 are the caps 17 rovided with the trunnions 18 each of whicli'seats within a bracket 12. The trunnion 18 and the "coacting Socket 18 of a bracket 12 are angular in cross section and snuglyengaged sov that, when the tubular memberv1v4 is appliedthe\same is maintained against rotation. When the tubular mem ber 14 is applied, the slot 15 is opposed to the pane P.

19 denotes an elongated strip of felt or kindred material of -a length substantially equalto the space between the inner ends of the appliedcaps 17. "This strip 19 is folded transversely with the 'folded portion inserted member 14 between-the overlying ortons of the folded stri 19, said rod 20 ing of a lengthto exten withinA the applied caps 17 whereby said rod 20 serves to maintain eectually the strip in ap lied position; This strip 19 is of such widlth that when it is fol ed and a plied within the tubular memlber 14, the ree longitudinal marginal portions thereof will extend exteriorly of the member 14 a distancesulicient to have contact with 4,the adjacent face of the pane P.

Byflexing the flanges 16, the contacting pressure of the longitudinal marginal portions of the strip 19 upon the pane P may be regulated as the necessities o practice may prefer.

When the wiping elements E are in applied position, both of such elements, together with the carriages C, constitute a unitary structure adapted to be moved lengthwise of the stiles S and S', the'base or intermediate portions 10 of the carria es traveling along the slots 7. Normally t e elements E are positioned immediately adjacent the upper rail R 'and by pulling downc turnedto their normal positions.` By this v wardl thereon, .the feltstrips 19 or the like wipe t e'faces of the pane P and which operation is true when the 4elements E are remeans, the faces of the pane P may be maintained clean.

In order to facilitate the. working of the elements E, one of the tubular members 14 is provided adjacent its opposite ends. with ,the outstanding handles 21 riveted or otherwise securely held in applied position. Normally arran ed between the strips 1 of each of the stiles is an elongated strip 22 preferably 'of wood and which is of a length to extend from the bottom rail R to` a distance below the upper; rail R substantially equal to the vertical dimension or length of a' carriage C. v This strip 22 is also of a width greater than the width of the slot 7 sothat said strip 22 operates to close the slot' 7. The inner marginal portion of the strip 22 is oppositely beveled or tapered to snugly engage. withinfthe ygroove, or channel 8 of a stile S. The innermarginal portion of the strip 22 is normally maintained seated within thel groove or channel 8 by the spring members 23 coacting with the opposite end portions of the strip-22 and anchored at one end to a metallic plate 4..v

When the elements E positions, they are maintained therein by the carriages C resting upon the upper ends of the strips 22. These upper end portions of thestips 22 are downwardly beveled, as

at 24, toward the stiles S so that when p ullh is imposed upon one of `thetubular members 14, lpreferably through the instrumentalityf of the handles 21, the strips 22 will be forced back between the strips 1 of the stiles S so that the base or intermediate portions 10 of slots 7.

are at' the Vlima of their upward movement or in their normal85` .the carriages will readily pass along the M improved sash construction is particioov may be assembled and operated, and it will n also be obvious that my invention is susceptible of some change and'modiication without departing from the principles and spirit to be understood as limiting myself to the precise arrangement and`formation of the..

several parts` herein shown in carrying out my invention in practice except as herein'v after claimed.

I claim:

1. A sash structure including stiles provided with slots extending lengthwise thereof, a carriage slidably mounted in each of the slots and including wings overlying the opposite faces of the stiles, a wiping element supported by the wings at each side ofthe structure, and lmeans for normally closing each of the slots, said means coacting with thereof and for this reason -I do not wish the carriages for normally maintaining the same at the limit of their movement in one direction..

2. A sash structure including stiles, each stile comprising a pair of transversely spaced members, a supplemental sti-le positioned adjacent each of the irst'named Stilesand spaced therefrom to provide an elongated slot, an elongated strip arranged be-L tween. the spaced members of each stile, means for constantly urgin said strip in a. direction to substantially closev the slot between the coacting stile and the ad'acent supplemental stile, a carriage slidab y engaged within each of the slots, and a wiping element connecting the carriages.

3. A sash structure includmg stiles, each -stile comprising a pair of transversely spaced members, a supplemental stile positioned adjacent each of the first named stiles and spaced therefrom to provide an elongated slot, an elongated strip arranged between the spaced members of each stile,

means for constantly urgin said strip in a direction to substantially c ose the slot between the coacting stile and the adjacent supplemental stile, a carriage slidably env gaged within each of the slots, and a wiping element connectingthe carriages, each of sa1d str1ps when 1n its normal position coacting with a carriage when at the limit of its movement in one direction for holding said carriage against movement in an opposite direction. l f

4. A sash structure including stiles, each stile comprising a pair of transverselyl s aced members, a supplemental stile positloned adjacent each of the rst named stiles and spaced therefrom to provide an elon- -said stripsv when in its normal position coacting ,witha carriage when at the limit of its movement in one direction for holding said carriage against movement in lan opposite direction, the end portion of each of the strips adjacent the carriage when in its normal position being beveled to permit said carriage to move along the slot and by the stri f Iii testimony whereof I hereunto affix my signature.
